Take a Stop Action Photo

Freezing a droplet of water or a smiling face zipping past you on a bike both require using a fast shutter speed and usually a higher ISO setting. I prefer to set my camera on aperture priority in order to prevent under-exposing my shot. In this shooting mode, using a wide open aperture like F/2.8, F/3.5 or F/5.6 will let a lot of light into the camera, and the camera will then automatically choose the fastest shutter speed it can—given the ISO setting and your lighting conditions. If it is a bright day, the shutter speed will be higher in this mode when using a wide aperture. And the higher you set your ISO, the higher the resulting shutter speed will be. So start with your camera in the “A” or “AV” mode, set the aperture to a wide open setting, and set your ISO at 400. Look thru the camera and see what shutter speed your camera says it will use. If it is slower than 1/500th of a second, then boost your ISO to 800, or 1000. Keep in mind that if your subject is moving very fast, you may need a very high shutter speed, like 1/1000th or 1/1250th in order to freeze the motion. To refresh your memory about aperture priority, take a look at the aperture download card posted here. Take a break from raking leaves, grab the camera and take a few shots of autumn fun. Or, if it is already snowing in your part of the country, take some creative snowball fight shots. Use a fast shutter speed to capture sports action, falling confetti, sprinkler water and more.
